IMAGE DISPLAY OPTICAL SYSTEM AND IMAGE DISPLAY

摘要

There is provided an image display optical system capable of setting the virtual image formation distance of an image display element at a finite value while ensuring a large exit pupil. The image display optical system (1) comprises a first optical element (2b) for parallelizing display luminous flux (L) emitted from each pixel of an image display element (2a), a substrate (11) for introducing the parallelized display luminous flux (L) and making it propagate inside, a plurality of parallel mirrors (11b) for deflecting and leading the display luminous flux (L) propagating through the substrate (11) to the outside the substrate (11), and a second optical element (13) for giving an optical power to the entire display luminous flux (L) led out from the substrate (11) so that the virtual image (I) of the image display element (2a) is formed at a predetermined position of finite distance on the back of the plurality of mirrors (11b).
